Optimization design method of elliptical contour sliding groove of automobile transmission shift shaft

The invention relates to an optimization design method of a straight shaft sliding groove of an automobile transmission, in particular to an optimization design method of a straight shaft elliptical contour sliding groove of the automobile transmission. A dynamic model of curved chute shifting block chute is established. The invention designs the dimension parameters of the drive structure of thecurved chute shifter chute, establishes the optimization design objective function of the best shape of the curved chute shifter chute, establishes the constraint conditions of the best shape of the curved chute shifter chute, and puts forward an optimization design method of the radius of the curved chute shifter chute and the height of the curved chute shifter chute. The optimum design variablesof the radius and height of the gearshift block of the curved surface gearshift slot are designed to provide the minimum drive torque of the gearshift drive gear acting on the gearshift drive shaft. 本发明涉及种汽车变速器直轴滑槽优化设计方法，尤其是种
